“…By following the cathodic and anodic curves, adding different concentrations of inhibitors will display a declining trend in the current, which indicates the tight restriction of the anodic and cathodic interactions, as shown in Figure 12 and Figure 13 . In addition, the lines are parallel when the inhibitors are added with the blanks, which proves that the reaction mechanism did not change by adding the inhibitors [ 37 , 38 ]. Additionally, there was a noticeable jump in the slope of the anode curve when changing the voltage values to the positive direction, which confirms the change in the absorbance values of the inhibitor.…”

The objective of this research was to explore the impact of corrosion inhibition of some synthetic acrylamide derivatives 2-cyano-N-(4-hydroxyphenyl)-3-(4-methoxyphenyl)acrylamide (ACR-2) and 2-cyano-N-(4-hydroxyphenyl)-3-phenylacrylamide (ACR-3) on copper in 1.0 M nitric acid solution using chemical and electrochemical methods, including mass loss as a chemical method and electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) as electrochemical methods. By Fourier-transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (1HNMR), and mass spectroscopy (MS) methods, the two compounds were verified and characterized. There is evidence that both compounds were effective corrosion inhibitors for copper in 1.0 M nitric acid (HNO3) solutions, as indicated by the PP curves, which show that these compounds may be considered mixed-type inhibitors. With the two compounds added, the value of the double-layer capacitance was reduced. In the case of 20 × 10−5 M, they reached maximum efficiencies of 84.5% and 86.1%, respectively. Having studied its behavior during adsorption on copper, it was concluded that it follows chemical adsorption and Langmuir isotherm. The theoretical computations and the experimental findings were compared using density functional theory (DFT) and Monte Carlo simulations (MC).

“…This table demonstrates that every computed adsorption energy is negative, confirming the spontaneity and permanence of these chemicals’ adsorption on the surface of Al. 46 , 47 Be noted that better adsorption results from greater adsorption energies (measured in absolute values). Additionally, Table 7 demonstrates that the E ads values for furanoeudesma and dihydropyrocurzerenone are identical to and higher than those for lindestrene, proving that they are crucial in inhibiting Al in an acidic medium.…”

Aluminum corrosion was inhibited by myrrh extract when it was placed in a solution of 1 M HCl. Several procedures were used for these tests, including weight loss WL, potential dynamic polarization PL, and electrochemical impedance EIS in addition to theoretical calculations like density functional theory (DFT), Fukui functions, and Monte Carlo simulation. Fourier transform infrared spectroscopy was used to analyze the compositional surface of Al. Scanning electron microscopy was used to determine the shape of the Al surface. The inhibition rate of Al corrosion in HCl with varying myrrh extract contents at 25–45 °C was studied. An analysis of the PL curves indicates that myrrh extract is an inhibitor of mixed type. Upon increasing the concentration of myrrh, the inhibition efficiency increased. Moreover, rising temperatures decrease inhibition efficiency. It was discovered that the inhibition process follows the Langmuir isotherm, demonstrating that a monolayer has formed on the surface of aluminum. Theoretical and practical studies proved the validity of the conclusions.

In the present study, CdSe Nanoparticles (NPs) as a corrosion inhibitor factor, has been added in small concentration (0, 1, 2, 3, 4 wt%) to nonionic surfactant to formulate CdSe/Surfactant nanocomposite (NCs) for industrial applications. The chemistry between CdSe (NPs) and surfactant, is a new class of corrosion inhibitors that are environmentally acceptable under various condition. The inhibition effect towards corrosion was investigated by using structural integrity and optical properties. The structural characterization was carried out by Fourier-Transform Infrared spectroscopy (FTIR), Nuclear Magnetic Resonance (NMR), Surface Tension Measurements (CMC), High Resolution Transmission Electron Microscope (HRTEM), UV–Vis Spectrophotometer and Atomic Force Microscope (AFM). The corresponding dielectric functions (DF) are discussed in the light of the optoelectrical parameters and dispersion parameters. The strong sorption ability of the CdSe (NPs)/Surfactant, resulting in the creation of a monolayer, which isolate the Carbon steel (CS) surface from the environment and hence reduces the corrosion attack on the surface and increase the absorption process as well. The values of the inhibition efficiencies (IE%), was explained in terms of the weight Loss, relevant electrochemical parameters, and charge transfer resistances. The values of (IE%) in this study, showed that it inhibits the (CS) corrosion when immersed in HCL solution to some appreciable extent, and is strongly dependent on the increase of the CdSe (NPS)percent. This work investigates and illustrate a way for the future development of higher performance of corrosion inhibitors.
